Abstract

Colony counter tools are used to count bacterial colonies. The high price constraint makes manual calculation the preferred alternative. In this study, Innovations were made to the SI PINTER tool by replacing the power source with a battery and using digital prayer beads connected to a marker to display the results on the screen. The purpose of this study was to develop the SI PINTER tool as a microbiology laboratory support to improve the accuracy of bacterial colony counts. Standardization of the SI PINTER tool is done by comparing the results of calculations using a conventional Colony Counter and without using equipment (manual) to get accurate results of the number of bacterial colonies. This research method is quasi-experimental and the data was analyzed by One Way ANOVA test. The results of the One Way ANOVA statistical test showed a p-value = 0.996 > 0.05, indicating that there was no significant difference between the results of the number of bacterial colonies using conventional Colony Counter, SI PINTER and manual calculations. The SI PINTER tool can be used according to its function as a microbial colony counter and has portable capabilities because it only relies on electrical energy from batteries

Abstract

This study utilized a quasi-experimental research design in the form of a pretest-posttest control group. It aimed to examine the impact of textbooks assisted by quartet cards on science literacy skills and student learning motivation. The research sampling was conducted through a simple random technique, selecting XI MIPA 5 class as the treatment group and XI MIPA 3 as the control group. Data was collected using multiple-choice tests to measure science literacy skills and questionnaires to assess student learning motivation. The descriptive and inferential analyses were conducted, employing non-parametric tests (Mann-Whitney) as the data analysis technique in this study. The results of the descriptive analysis illustrated that students taught with textbooks assisted by quartet cards exhibited science literacy skills in the medium category, while their learning motivation was rated as very high. Based on the results of the inferential analysis, a significant difference was observed in the science literacy skills and learning motivation between students using textbooks assisted by quartet cards in the treatment class and those in the control class. The mean rank number in the treatment class consistently exceeded that of the control class in Biology at SMA Negeri 1 Wonomulyo. One limitation of the research is the shortage of quartet cards available for the learning process, which resulted in students taking turns rather than playing simultaneously. To address this, the teacher should prepare additional sets of cards, each accommodating four students, and effectively allocate time during the process of playing cards and answering questions in the textbooks. This will ensure that the learning process runs efficiently and effectively.

Abstract

Copyright©2023 The low interest and motivation in learning that students have during the learning process can be seen by the lack of participation of students in expressing their opinions it affects the learning outcomes of the students themselves. This study aimed to determine the differences in interest, motivation, and learning outcomes of students through the PBL model and the STAD-type Cooperative Learning model. This research was a quasi-experimental study using a pretest-posttest control group design. The sample in this study were students of class XI MIPA taught using the PBL model and the STAD-type Cooperative Learning model. Data collection was carried out by filling out interest, motivation, and learning achievement tests twice, namely the pre-test and post-test. Data analysis was carried out descriptively in the form of N-Gain measurements of normality and inferentially in the form of Normality tests, Homogeneity tests, and independent sample t-Test Hypothesis Tests using the SPSS version 24 system. From the results of this study, it concludes that there are significant differences in interest, motivation, and learning outcomes of students with the application of the PBL learning model and the STAD-type Cooperative Learning model, where the application of the PBL model shows a higher post-test average value than the post-test average value of the STAD Cooperative Learning model so that the PBL model is more effective for use in increasing the interest, motivation, and learning outcomes of students.
